When summertime heats up, it's time to ditch those heavier, darker dress shirts and find something more "beach friendly" for your nighttime escapades, like the Banana Republic Slim Stripe Shirt ($60). It features a classic, clean button-up front with laid back details like a spread collar, triangular side gusset for flexibility, and a wrinkled look so you won't get all sweaty simply trying to make your shirt look good. Just throw it on, grab a Corona (hey, it is Cinco de Mayo after all) and relax.
